This means the same thing as y = 3x + 11 AND y = -2x + 1
hey! :) 3x+11=-2x+1 can you solve this?
So you can set them equal, as myininaya has done.
so all i havta to is solve that euation?
solving that equation will give us x
and then when we get x we plug it into one of the equations given to find y
therefore finding the point of intersection (x,y)
so if you want to try to solve for x i will do the same and i can tell you if you are right but if you run into trouble we can solve together okay?
3x+11=-2x+1 +2x +2x 5x+11=1 -11 -11 5x= 12 ___ ____ 5 5
so 1-11 is 12 ?
what is 11-1?
so we have 5x=-10
brilliant! :) now plug this into one of the equations given to find y like this y=3(-2)+11
i just replaced x with -2 since x=-2
now you are to simplify 3(-2)+11 to find y
well 3(-2)+11 is y i just mean simplify lol
that is totally correct
Thank you!! XD
if you had used the other equation you still would have got same thing by the way
great job! you get a medal!
Your the best!, thanks :D
